Be it known that I, WALTER C. WEs'rA- WAY, a citizen of the United States, residin at Rockford, county of Winnebago, an State of Illinois, have invented certain new and useful Improvements in Carbureters', of which the following is a description.

My invention be ongs to the general 'class y of devices designed to thoroughly commingle air and a suita le liquid; such for example as a hydro-carbon, for any desired purpose, and has for itsobject the production of simple and ellective means for the purpose.

To this end my invention consists in the novel construction, arrangement and 'combination of parts herein shown and described and more particularly pointed out in the claims. In the .drawings wherein like reference characters indicate like or corresponding parts, Figure 1 is a vertical sectional view showing my improved carbureter, Fig. 2 is a bottom plan of the same, Fig. 3 is a plan view of the valve seat, dotted lines indicating the relative position of the conductin groove in the valve connected therewith,l `g. 4 is a plan "view of the valve, Fi l5 is a view of a modified form of cam mem er, Fig. 6 is a bottom plan of the same, and Fig. 7 is another form of adjustable cam.-

In the preferred form shown in the drawings, 1 re resents a suitable base and 2 a top or. casing torming -a mixing chamber. The two may be secured to `ether 'in `any preferred manner.. As shown ugs3';3

formed upon the two parts and registering with one another serve as seats for'suitable clamping bolts (not shown) which firmly secure the two 'parts to ether. .The base is preferably formed wit a cireularfo ening in 'to which fits a bottom piece '4 Awlich slightly smaller than the opening in the base forming an annular inlet 5 between. the two` for the hquid.' The bottom iece\4 is se'- cured 1n position by suitable!v 'its 632-6 or equivalent means. An opening 'Zis formed in the bottom piece 4wh1ch serves'as an air inlet While 8 serves as an'outlet"forJ the/shell;

Anoiiset or extension 9 has formed-thereon a.l valve seat 10 tending provided with a duct 1 landexf* sect and a second duct 1 3 extending from, e

valve seat to the inlet 5.. .A-valvestent'14 extends through the valve vseat andnarris la `valve 15 and a cam 16 a--spring- 17 or'cquiva'-l .-1

from the nquidsupply pipe/i12 tvth tioned within a recess formed within the exf tension for that urpose. A valve 18 ar ranged to cover t e air inlet 7 is preferably hinged to the bottom piece 4 and 19 and is provided with an arm .20 extended 1n 'the ath of the cam 16. `A support 21 carried by the bottom 4 supplies a seatfor a s ring 22 4positioned between the support an the valve 18, serving as resilient means to normally hold the valve closed. The valve 4stem 14 is supported in a suitable bearing 23 carried by the top 2, and a handle 24 serves as means for o ratin said Vvalve stem.

The mode o operation as thus described is as follows: Normally the solid ortion of the valve 15 covers the port 1l an prevents the passage of li uid into the mixer. lUpon rotating the va -ve stem 14 the groove 25 registers with the ducts 11 and 13 and permits the iuid to. pass from the supply pipe 12 to the.

inlet 5. By the same movement the cam 16 operates the lever 2 0overcoming the l Hspring 22 and partially uncovering the air et 7.

It will be obvious that the extentr to which. either of the -valves is opened depends upon the rotation of the valve stem 14 and that the two inlets are opened synchronously and the duct 13.' As the valve is further rotated the groove further uncovers the inlet 11 ove irst registers with the inlet 11 it cuts y the. opening permittin -a small quantity of the uid to enter and e gradually conducted to.

bringing the larger and .deeper portions of the. groove into complete registry therewith perter.v

valve ,and'b'y thisI rotation the air valve 1s larger quantities of the fluid to engifrrespondingly opened so that as the liquid isfincreasedfso also is the air. `In the Pff" Vv'ferredfconsdruction a small lduct 26 1s formed in 4the air valve 18 permitting any accumulated fluid when -t e device is not his requires the rotation of the inlet llos the escape of 'in operation and atfthe same time permitting a sxnall quantity of air" to.v enter and mingle with any accumulated fluid so that a small qtiliantityof the carbureted air is retained in t e device which may be utilized in starting up the operation.

and resting upon the extension 9 prevents the accidental disengagement of the valve 15 from its seat.

- in the vairinlet.

- The cam 16 is preferably adjustable so that the extent to which the air valve will be operated may be regulated as desired. This may be accomplished either by releasing the set-screws 28 and rotating the cam member 16 around upon the valvelstem to bring the higher part of the cam earlier into action with the arm 20 when by again setting the set-screw the arts may be firmly connected, or it may be one by providing means for re ulating the inclination of the cam surface. his result may be secured in any desired manner, one simlple means being shown in the drawings. n Figs.' 5 and '6 the cam member comprises a plate 29 provided witha series of bolts or screws 30 the ends of whih project to form the cam surface. By adjusting the screws or bolts 30 as desired the inclination and height of the cam may be regulated asA desired.

In the preferred construction a spreader 31 is positioned within the mixer and normally serves to substantially close the li uid inlet 5 as well as the air inlet 7. Gui ing means carried by the spreader serves to direct it in its operation. These consist in a stem 32 loosely positioned in a seat carried by a plate 33 and in lugs 34 loosely positioned A spring 35 serves to resiliently maintain-the s reader in its normal position the operation being insured byf the action of the engine or a vcoperating pum connected therewith. This give a p sating action the spreader being eriodically ylifted from its seat permitting t e inflow of the regulated quantities of uid and air u on Iretur to its seat will contact with t e inflowing hquid and spread the same out into a iilm between the proximate parts over wlu'ch the inflowing current of air 1s directed at the next movement. may be employed if desired, to insure a more `perfect mixture of the-inlowing air and liquid. The supporting plate 33 may serve as one of the series of baflie plates.
